OnWorks Oracle Linux online is an enterprise-class Linux distribution supported by Oracle and built from source packages for Red Hat Enterprise Linux (RHEL). Some of the special features of Oracle Linux include a custom-build and rigorously-tested Linux kernel called "Oracle Unbreakable Kernel", tight integration with Oracle's hardware and software products including most database applications, and "zero downtime patching" - a feature that enables administrators to update the kernel without a reboot.
As you can see in this OnWorks Oracle Linux online the Oracle Linux operating system is engineered for open cloud infrastructure. It delivers leading performance, scalability, reliability and security for enterprise SaaS and PaaS workloads as well as traditional enterprise applications.
Oracle Linux delivers advanced features for supporting and optimizing the latest enterprise hardware and software. For example:
- Ksplice Zero Downtime Updates – Available to Oracle Linux Premier Support customers, Ksplice technology updates the Oracle Linux kernel and critical user space libraries without requiring a reboot or interruption. Only Oracle Linux offers this unique capability, making it possible to keep up with important kernel and user space updates without the operational cost and disruption of rebooting for every update.
- OpenStack – OpenStack is management software for deploying and managing public, private and hybrid cloud infrastructure. It can be used to automate deployments of popular Oracle software products such as Oracle Database and Middleware. Oracle OpenStack is open source, free to download and available as part of Oracle Linux Premier Support at no additional cost.
- XFS File System – XFS is a journaling file system known for extreme scalability with near native I/O performance. XFS is the default filesystem for Oracle Linux 7. Beginning with Oracle Linux 6.4, customers with Premier Support subscriptions can receive support for the XFS file system at no additional charge.
- Data Integrity – Oracle Linux supports the T10 Protection Information Model (T10-PIM) to help prevent silent data corruption.
Running Oracle Linux with UEK gives you additional advanced features and security enhancements. Some of which are:
- Containers and Orchestration – Safely and securely run multiple applications on a single host, without the risk of interference with each other. Docker containers are lightweight and resource friendly, which saves on rack space and power. Oracle Container Runtime for Docker and Oracle Container Services for use with Kubernetes provide a comprehensive container and orchestration environment for the delivery of microservices and next generation application development.
- DTrace – DTrace is a comprehensive dynamic tracing framework that provides a powerful infrastructure to permit administrators, developers and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs in real time.
- Oracle Cluster File System 2 (OCFS2) – OCFS2 is a general purpose, extent-based clustered file system that Oracle developed and contributed to the Linux community. It provides an open source, enterprise-class alternative to proprietary cluster file systems, and provides both high performance and high availability.
